Title: LRGB can not access the images in the drop down menu
Post by: emelan on 2016 August 16 22:17:04

Hello
    I can not load the images I want in the download drop down menu of the LRGB combination tool. When I down load the images I want to combine the only image I can load is the luminance image. No other option is available. I am using windows 10 and I have restarted PixInsight and the computer but nothing I have done will reset the menu.

Are you sure that the other images are greyscale?
You can read the color space in the top bar of the image.

Elliott,

I am assuming what you want to do is combine your Luminance image with your RGB image.  You will want to have built your RGB image in the first instance using the ColorCombination and then adjusting it with Background Neutralization and ColorCorrection in the linear stage.  When you get to LRGBCombination then, you simply load up the Luminance image and then drag the little triangle in the lower left of the toolbox unto the RGB image and it creates the LRGB image from those.

Hope that helps.

Jim

Thank you gentlemen that was the problem I was converting the EGB images to colour and that is why they were not showing up in the drop down box.
